Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automation networks face delays and collisions in data packet transmission due to complex topologies, leading to increased network occupancy time and reduced performance, with existing methods requiring substantial computational effort to achieve suboptimal results.
Innovation Solution
A method for arranging data packets in an optimized transmission order that minimizes total occupancy time by performing a finite number of pairwise permutations, allowing for efficient data communication with reduced computing capacity, where data packets are ordered based on circulation duration and receipt time markers to avoid collisions and delays.

Engineering Contradiction Analysis
1Productivity
If data packets are transmitted in complex network topologies without optimization, then data communication can occur, but network occupancy time increases and performance decreases due to delays and collisions
Solution Approach 1:
The patent applies preliminary action by determining an optimized transmission order for data packets before actual transmission occurs. The master subscriber calculates circulation durations for multiple transmission paths and establishes an optimal sequence in advance, which minimizes network occupancy time and prevents collisions before they happen. This pre-planning approach directly reduces the loss of time during data communication.
2Loss of time
If existing optimization methods are used to reduce network occupancy time, then some performance improvement is achieved, but substantial computational effort is required
Solution Approach 1:
The patent implements self-service by enabling the master subscriber to autonomously determine optimized transmission orders using its own computational resources. The system calculates circulation durations and optimizes packet sequences without requiring external computing units or additional hardware. This self-service approach reduces device complexity while effectively minimizing network occupancy time through intelligent algorithms.
3Productivity
If data packets are sent without optimized ordering, then transmission can proceed, but collisions and delays occur reducing overall performance
Solution Approach 1:
The patent applies feedback by using circulation duration information to continuously optimize transmission orders. The master subscriber monitors the actual circulation times of data packets through the network and uses this feedback to adjust and refine the optimized transmission sequence. This feedback mechanism ensures both high productivity and reliability by preventing collisions and ensuring timely delivery of control packets.
